This invention relates tozmachines for use in the binding and backing ofbooks or the like.

An object of the invention is to provide a binding-machine having a visecomprised of a stationary and a movable jaw, foot-operated means beingprovided to quickly move the movable jaw into engagement with an objectto be held between the jaws, whence the vise may be tightened by hand inthe usual manner. I

Another object is to provide a device of the character referred toprovided with means, to automatically return the movable jaw to its openor normal position when not.

in use.

A further object is to provide a device of the character referred tohaving the usualvise screw and hand wheel secured thereto,

a loosely mounted nut being carried by the screw between the hand wheeland the movable jaw of the vise, whereby movement of the hand wheel willcause the nut to engage the movable jaw andretain said jaw in engagement with an object placed in the vise.

Other objects and advantages will become apparent during the course ofthey following description.

In the drawings I have shown several embodiments of my invention. Inthis showing:

Figure l'is a side elevation,

Figure '2 is a central vertical section with the lower parts brokenaway,

Figure 3 is a plan View,

Figure 4 is a front elevation, and,

Figure 5 is a central vertical section of a modified form of theinvention with the lower parts broken away,

Referring to the drawings the numeral 10 designates the frameofthemachine adapted to receive a suitable bed 11. A vise is mounted on thebed 11 and consists of a stationary jaw 12, preferably formed integralwith the bed and having a vise plate 12; secured thereon, and a movablejaw 14: having a v se plate 15 secured thereon. As shown in Figures 1 to4 of the drawings the jaw members 12 and 14 are inclined with respect tothe horizontal plane of the device, the member 12 being slightly higherfor a purpose to be described.

1928. Serial No. 276,773.

Preferably formed integral with the jaw 12 and on each side thereof, andarranged at an angle to the bed,'is a guide arm 16. As shown in Figures1 and 4, the sides of the jaw member 14 extend outwardly of the bed andhave a downwardly projecting portion 17, which engages the guide arm 16.A suitable plate 18 engages the bottom of the arm 16 and, portions 17,and is secured by bolts 19 or the like, to the portions 17 whereby achannel is formed surrounding the arm 16. It will readily be seen thatthe jaw member 14 is mounted for sliding movement on the guide arms 16.Depending from the jaw 14 and substantially centrally thereof, is a pairof spaced ears 20, preferably formed integral with the jaw, suitableopenings being provided adjacent the lower extremities of the ears toreceive a pin or shaft 21. 'A pair of rollers 22 are mounted on the.shaft 21 outwardly of the ears 20 and these rollersare held on the shaftby cotter pins-or the like 23. The frame 10 is provided on its sides andsubstantially centrally thereof with preferably integral arms 24,carrying suitable jour 7 nal boxes 25 inwhich are rigidly secured abearing rod 26, by means ofset screws-27 or. the like, threaded intosaid journal boxes and engaging said rod. A relatively large lever 28,having a forwardly extending portion 29, is pivotally-mounted on the rod26. shown in Figure 4, the upper extremity of the lever 28 is bifurcatedand the pivotal connection. with the rod 26 is made through the arms 80.Set screws 31 or the like extend through the arms 30 into suitablegrooves in .the rod 26 whereby the lever may pivot with respect to therod but is incapableof longitudinal move ment thereon, as will beunderstood, The arms 30 extend upwardly asubstantial distance' above theshaft. 21 and each armis adapted to engageone of the rollers 22 .QA footpedal 32 is arranged on thefforward extremity of the lever. It will beapparent that when the lever is depressed the armsSl) thereof willengage the rollers 22 and slide the movable jaw into engagement with thestationary jaw. If the lever is released the movable jaw will return toits normal-or open position by grav ty because of ts inclined V relationwith the stationary jaw. A vise screw 33, mounted in asuitable bearing34 i and carrying the usual hand wheel 36, is arranged rearwardly of themovablejaw 14.

As shown in Figure 2, a recessis formed in the movable jaw and the innerextremityof is-ada ted to extend into this re} cessr Miii i nt ed on thescrew 33 and provided with threads in which said'screw operatesg'i's apreferably rectangular nut .or block 37:, and a pair of relatively wideside plates 38 are securedto the jaw member 14, by bolts 39 or the like.These plates 1 prevent the nut 37 from turning and they extendrearwardly 21 suflicient distance to I prevent rotation, of the nutwhnthe jaw 14 is in its forward or.
